Q. Which of the following is most reactive towards electrophilic nitration?
A) Toluene
B) Benzene
C) Benzoic acid
D) Nitrobenzene
Explanation
(a)
Due to $+ I$ effect of $CH_{3}$ in toulene, it is more reactive than bezene. Due to electron withdrawing nature of $–COOH$ group in benzoic acid and $–NO_{2}$ group in nitrobenzene, both benzoic acid and nitrobenzene are less reactive than benzene.
